As the temperature of the water shower is less than dew point temperature hence, water vapour starts condensing. Thus, the process involved is cooling and dehumidification.

The process involved in this scenario is cooling and dehumidification.
Explanation:
1. Definition of dew point temperature: The dew point temperature is the temperature at which the air becomes saturated and condensation begins to occur, forming dew or fog.
2. Given conditions:
- Dry bulb temperature (DBT) = 35°C
- Dew point temperature = 25°C
- Water shower temperature = 20°C
3. Comparison of DBT and dew point temperature:
- The DBT of 35°C is higher than the dew point temperature of 25°C.
- This indicates that the air contains moisture and is not saturated.
4. Cooling process:
- The air passes through a water shower with a temperature of 20°C.
- As the air comes into contact with the cooler water, heat transfer occurs from the air to the water.
- This results in the air temperature decreasing.
5. Dehumidification process:
- The difference between the dew point temperature and the water shower temperature is 5°C (25°C - 20°C).
- When the air temperature reaches the dew point temperature, the air becomes saturated and condensation begins to occur.
- As condensation occurs, the air loses moisture and becomes dehumidified.
Conclusion:
The process involved in this scenario is cooling and dehumidification. The air is cooled as it passes through the water shower, and at the same time, it loses moisture and becomes dehumidified when it reaches the dew point temperature.
